The difference between the climate change that takes place over long geographical periods and the present climate change brought about by global warming is that whilst the former is a natural phenomenon, the latter is anthropogenic or man-made in origin.
The earth’s temperature is the product of a ping-pong game between the sun and the earth. The sun constantly and continuously gives off energy in the form of sunlight and radiates it to the earth’s atmosphere. The solar energy that touches the earth’s atmosphere is either absorbed by some of the earth’s particles or transmitted. The heat that reaches the earth’s surface is then emitted back to the atmosphere as infrared radiation. However, not all of the infrared radiation successfully passes out of the earth’s atmosphere because some atmospheric components absorbs and therefore prevents infrared radiation from entirely leaving the atmosphere, The trapped heat is then eventually reradiates back to the earth’s surface (see Fig. 1). Such heat-trapping components are called greenhouse gases and the process of absorbing, trapping and reradiating infrared heat to the earth’s surface is called the greenhouse effect. The greenhouse effect is what sustains life on earth because without it earth would be more than 30°C colder than what it should be and therefore, inhabitable by humans, animals and plants. The present global warming is attributed to the more than usual amount of heat trapped and reradiated back by the greenhouses gases to the earth’s surfacea (Great Britain: Department for Environment, Food and Rural Affairs 2006 8; Ebbing & Gammon 210; Hardy 2003 3).
There are two classifications of gases found in the earth’s atmosphere: the primary gases made up of nitrogen, oxygen and argon which make up 99% of the gases, and; the trace gases like carbon dioxide (CO2), methane (CH4), carbon monoxide (CO), nitrogen oxides (NOX),

There has been a considerable change in the global climate as witnessed by rising temperatures, longer periods of summer and winter, cyclonic storms, hurricanes, severe droughts, and floods. Scientists, engineers, environmentalists, and political leaders show helplessness as people continue to die because of drought-induced starvation and flood-induced epidemics in densely populated areas.
atively related to each other. As indicated by the positive slope of supply function and upward sloping supply curve, price and quantity supplied are positively related to each other. These relationships are same as supported by the theory of demand and supply that quantity demanded has negative (or inverse) relationship with price while quantity supplied has positive (or direct) relationship with price.
(The greenhouse gases of the majority concern are Carbon Dioxide (CO2), Methane (CH4), with nitrous oxides.) The recent consequence that climate modify has had is the equal of a 1 watt light bulb burning over each square meter of the earth (Brown BE, 163-170).
Indeed, the sustainable development approach of the 1970s and the issues posed by climate change more recently have raised significant challenges to the dominant modernist development paradigm. It has therefore, become
The importance of reducing the emission of greenhouse gases in the United States of America hardly needs to be emphasized as in many cases, it has set the precedent for the industries of the world. Here too, the environmental
According to the research findings, it can, therefore, be said that Abercrombie & Fitch (A&F) have encountered huge fall in business ranking as they could not respond to the changing desires and needs of the customers. The paper tells that its consequence is fatal to the company as it lost its position in the market.
Globally, at least 250 million people are faced with natural related disasters annually (Sivakumar, 2005, p. 10). It is estimated that this could increase to at least 375 million people who are likely to be face by environmental related challenges at least in the next
